YouTube has warned its creators that they are going to "see a noticeable decrease in your subscriber count" today when it bans hordes of spam subscriptions from the platform. This action is being taken to verify the legitimacy of accounts and actions on YouTube channels. A bug has been fixed that didn't allow for spam subscriptions to be removed from the system. "Removing spam from the platform helps ensure that YouTube remains a fair playing field for everyone and should result in higher confidence that you're organically building a community of authentic fans." What if I have fallen below the YouTube Partner Program (YPP) threshold of 1,000 subscriptions as a result of the removal? Channels that had a high percentage of spam and fall below 1,000 subscribers will no longer meet the minimum requirement for YPP and will be removed from the program. They are encouraged to reapply once they've rebuilt their subscribers organically. You can learn about how to apply for YPP here.
